Clarification about the term "GPS Shutdown"

I have yet to see this, although I suppose it's possible.

Of course, compasses have the same problem.

 

Quite comparable, since it would usually correspond to a power failure.

So what's the backup for that?

 

At least hours.

 

No, it is equivalent to saying it's not critical (for those
who plan properly), as opposed to merely useful.

As always -- Proper planning prevents piss-poor performance.
Don't allow yourself to get into a life or business threatening
situation without fully assessing the risks.

 

As already pointed out, lungs can also be really necessary,
without which the heart doesn't have much to contribute.

In your case, impaired brain function (i.e. the gross
inability to accept anything which contradicts your notions, even when
presented by people vastly more knowledgeable than you) does not seem
to be a completely debilitating deficit.

I suggest consulting a philosophy book to bone up on the
distinction between necessary and sufficient causes.

 

This is, in any case, begging the question (or circular
argument, if you prefer). It makes as much sense to communication
without a pencil is impossible because you've defined pencil and paper
as one form of communication.

 

Poor navigation is only a single, and perhaps not very
significant, contributor to the number of ships on the bottom of the
sea. Severe weather and sub-optimal seamanship are much more likely
causes.

 

No argument there, but I believe Alan was referring to
reducing speed well before entering an area of heavy traffic.

 

There's a much more severe limit on how _fast_ they can go and still
get the job done.

 

Keeping the required adequate lookout and use of radar will do
far more than a GPS unit for avoiding collisions.

 

Only a lunatic believes ships without GPS must go "where they
don't belong."

 

Touche! Electricity suffers many interruptions. Life goes on.

 

You have just outdone yourself in terms of asking silly-ass
questions.

 

No, dodo -- a battery or a shot from an air compressor.

 

Not to mention diesels running generators can be kept online
and transfer as rapidly as required.

Now fire up your little forklift and move the goalposts for
the fortieth time to a ridiculous new location.

 

When in doubt (and especially when irrevocably refuted),
redefine the problem to suit your taste.

 

Or a ship owner who has lost valuable property to piracy or theft.

 

Does it? Not where I live.

 

Without fuel?

 

A ship will still report its position after being stolen by pirates?
Only if the pirates are extremly stupid...
